sad not sure about the fake Lego. Or the prostitution of a historic brand. Or the miss-use of Steampunk.

Its a shame they can't use the BL name for something better.

Thread: Pins for a knurling tool - how hard should they be?
18/04/2021 14:56:51

You don't need to harden the pins.

All journals benefit from having the cheap part softer, and they can even last longer as a result, so mild steel will be sufficient.

Its difficult to imagine an amateur wearing the bore of a knurling tool such that it does not work, so any accurate material will do for what you need. smiley

If Broadswords top speed was only 30 knots, how was its acceleration quite so good??

Thread: Problem with 4 jaw chuck
14/04/2021 14:11:57

Strip it down and get a square onto those jaws, you can't fix what you can't measure.

I suspect that they will need re-machining, the best method will depend on what you have access to.

Nigel - I bought an HP Office Pro 7730 a similar wide format printer coupled with an A4 scanner ( + the small extension to handle American paper but obviously inadequate for A3 scans) - cost ?1.50 at auction, my intention was to scrap it for parts - it came without any print cartridges - but the scanner worked well under Vuescan the linux CUPS system machine recognises the printer - how much are the cartridges counterfeit or otherwise?

Remarkably expensive!

embarrassed thanks John and John.

Hopefully my COVID-addled brain will one day be able to connect words with concepts as badly as it did before. I am beginning to think I may have to accept it as the norm though.

Hi Jim

You don't actually have a problem wrt DRO. The cross slide, as Duncan says, is mainly to facilitate some of the more complex processes, especially increasing depth of cut on a thread, for which setting it to 30degrees, (or 60 depending on your lathe) is ideal.

If you watch Ade's workshop he is particularly good at explaining the use of the DRO for incremental cuts. I am sure that as you use your machine you will get used to making fine adjustments and getting sub-thou' cut adjustments as a result.

Thread: Buying advice sought re Milling Machines: e.g. Proxxon: FF230 vs. BFW40/E vs. MF70
31/03/2021 21:48:20

I have some friends with small Proxxon MF70 mills and they love them. They are ideal for small modelling work in softer materials. One of them bought a pillar drill within weeks if I recall correctly.

I was looking about that time and it never occurred to be to go so small and light, because I was already focussed on steel and doing relatively-precision engineering, so I knew I had to pay for pounds weight and put up with a permanent installation.

However all I have done in since I got it could have been on on the Proxxon, and most of what I will do could be. It really does come down to what you want to do with it.

Hi everyone!

I'm a mum here seeking some guidance for how to help my son into building his own steam locos.

He's just turned 11. Has been steam mad since he 1st saw Thomas, and this interest has turned passion (he's a keen playing of train sim World and train sim)

I have enquired about him helping at our local heritage steam line but as expected insurance prevents this until he's older so I'm wondering if model engineeringay be a path to follow?

 

Can anyone suggest a good starting kit with good instructions? (That won't instantly bankrupt me)

He's reasonably bright (has thrown together the kego technic kand rover defender with no issues and no help) but both myself and his father ate creative and mechanically minded so happy to help and guide him where and when needed.

Thank you all!

Viv

Without a doubt the Wilesco kit is a great start, a Mamod kit is even simpler and more idiot proof but less flash. There are few build threads on the Unofficial Mamod Forum and lots of modified examples.

I like quick results, just like an 11 year old, so I like toy engines too, I can't recommend the fun of running one enough. If the exercise is successful then move on and up to more elaborate things.

Thread: Milling machines - western-made s/h recommendations up to 2k
29/03/2021 17:55:39

I appreciate your moral stance William. Not sure which new British-made machine satisfies all the criteria, but if second hand is good enough there is plenty of suggestions above and reasonable market, so patience will be rewarded I suspect.

Sports cars are a lot of fun for 8 months of the year, I would rather have both a car and a cheap milling machine that an expensive milling machine.

Thread: Is RSJ Steel machinable?
24/03/2021 21:13:58

I had a hell of a job drilling holes in an RSJ for my house. 275 is proper strong stuff and the cheap drills didn't like it.

Sell for its proper use and buy something useful I say.

I had a beam outside for a decade. A good coat of red oxide and bitumastic paint kept it in good condition.

Thread: Pressure Turning
24/03/2021 20:59:33

Just don't stand in the way! smiley

A common technique I will undoubtedly try someday. I am pretty sure the trick is to minimise cutting forces, that means tiny feeds, sharp tools, cutting off a ring, etc, etc.

3mm sounds a bit chunky, but I don't see why not, just work across the face maybe having cut off the excess with a jigsaw.

As it is saving a huge amount of filing time I am sure its worth being careful.

Yes please Herbert.

Thread: Inherited ML7 in need of some love - where to start?
05/03/2021 14:20:50

Hi Tom

The main machine looks to be in good condition, so I suggest you follow the cautious chap's advice on that.

The bits that have been taken off look worse, however they are more easily stripped and cleaned.

There are few YouTube videos on stripping and de-rusting chucks that would be worth following. Its not difficult and using a chuck with rust in the internals will kill it.

I think you should expect to get it working in about 40 hours. Get some pleasure and pride out of it, Then allow yourself to slowly bring it up to what you want over a few years. A full-restoration could be 200+ hours even for the skilled, even more of you go full-hog.

Cheers

Rog
